IMPROVEMENTIN MACHINES FOR CUTTING OFF GELATINE CAPSULES.

Specification forming part of Letters Patent No. 187,279, dated February13, 1877; application filed April 17, 1876.

To all whom it may concern Be it known that I, FREDERICK A. HUEEL, ofDetroit, in the county of Wayne, in the State of Michigan, have inventeda new and useful machine for cutting off at a required and uniformlength empty gelatine capsules, preparatory to their being removed fromthe molds upon which they are run; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, and the letters ofreference markedthereon, making a part of this specification.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Figure 1 of the accompanying drawing is a front view of the machine. 01d are circular knives. s s are springs pressing the knives against themolds c c. l l are screws holding the springs s s to the cog-wheels b b,as shown in Fig. 6. O is a crank, inserted into one of the cog-wheels. Dis a platform, moved up and down by the slide F, cog-wheel T, and leverH. L is a upon the cylinder K, with screw and crank,

- as shown in Fig. 3. R C e e is a set of molds placed upon the movableplatform D, for cutting the coating of gelatine, e" c.

Fig. 2 is a plane view of the upper plate, showing the knives in theirposition after the crank 0, Fig. 1, has been turned one-half round.

Fig. 3'is a sectional view of the machine at the line an ac, Fig. 1.This shows the position of the knives d d when the cut is about to bemade. This figure shows the construction of a set of molds. c is an ironplate. 0 e are molds of steel, fastened into it by the nuts 1; i. R is aboard,into which these nuts are let in and which is fastened to theplate 0.

will now give or explain the mode of operation Let the projection u beturned down, so that the surface of the tube L is level with theplatform D; place the set of molds R C e e, Fig. 3, upon the platform ina position that the projection from a tube, moving 5 molds e e standdirectly below the spaces between the knives d d; raise these molds tothe required height up into these spaces by the lever H, (thearrangement L K S is fastened to the platform and rises and falls withit.) Turn up the projection u to the position in the ligure. The crank sis now turned, pressing the molds e 6 against the knives d d, as shownin Fig. 6. The crank O is now turned, causing the knives d d to performthe cut, as shown in Fig. 6. When the cut is made the molds e c areagain raised up by the lever H, and the part of the coating 6 Fig. 6, isshoved away from the upper part c, Fig. 6.

Fig. 4 is a plane view of a set of molds.

Fig. 5 is a plane view of the upper plate of the machine, showing thecog-wheels in their position.

Fig. 6 is an enlarged view of one of the cutters and molds, and theshape of the capsule after it has been cut off, as has been described,as aforesaid, and separated from the part out off and prepared to beremovedfrom the mold.

I do not claim the molds upon which the capsules are run, and upon whichthey are during the operation of cutting them ofi. as described, as partof my invention; nor do I claim, as part of my invention, thecomposition of the gelatine in which the molds are dipped to form thecapsule but What I claim as new, and desire to secure by Letters Patent,is-

The machine for cutting the capsule off at a required and uniform lengthafter the mold is dipped into the gelatine, and while the capsule isstill on the mold, and preparatory to its being removed therefrom, asherein before described, and consisting of the circular knives, workingin connection with the springs, screws, cog-wheels, crank, platform,slide, lever, and cylinder, as described herein.

FREDERICK A. HUBEL.
